These are the season and episode counts for all seasons and series released so far, ordered by the date that they were initially released. Series with an N/A for the "Last released" date are still in production.

Big Finish's current licence from the BBC allows it to produce audio dramas featuring the first twelve incarnations of the Doctor and associated characters introduced into the series between 1963 and 2017. However, it does not allow the use of the current Thirteenth Doctor (Jodie Whittaker), or any characters which originate from her era.[3]

Several actors who played the Doctor and companions of previous Doctors have appeared in other roles, including Russell, O'Brien, Marsh, Wills, Watling, Padbury, Caroline John, Manning, Elisabeth Sladen, Leeson, Daphne Ashbrook, Tennant and Bernard Cribbins. Sladen also reprised Sarah Jane Smith in a spin-off series simply entitled Sarah Jane Smith. Sladen never appeared as Sarah alongside any incarnation of the Doctor for Big Finish; a series with Tom Baker was planned, but was never recorded due to Sladen's untimely death in April 2011.

Big Finish also started The Companion Chronicles series of plays, featuring a companion or friend of the Doctor and a supporting cast member. Ford, Russell, O'Brien, Purves, Marsh, Wills, Hines, Watling, Padbury, Manning, Jameson, Tamm, Ward, Sutton, Strickson and Aldred have all reprised their roles in this series along with John (Liz).

In January 2007, a new series of Eighth Doctor audio adventures was broadcast on BBC7. These starred McGann alongside Sheridan Smith as the aforementioned new companion Lucie Miller. There were eight 50-minute episodes in total; the first and last stories were two-parters, and the rest were single episodes. These adventures have since been released on CD. In 2008, BBC7 broadcast the second series of The New Eighth Doctor Adventures (which Big Finish had already released on CD) bar the final two-part story. All fourteen episodes were then repeated in 2009, and the final two-part story later that year. Big Finish has gone on to produce two further series of these Adventures, and four selected stories from the third series were aired in 2010, with BBC Radio 4 Extra (as Radio 7 became) skipping ahead to the fourth series in early 2013.

In May/June 2011, BBC Radio 4 Extra broadcast the Fifth Doctor stories Cobwebs, The Whispering Forest, and Cradle of the Snake. In May/June 2012, these were followed by the Seventh Doctor stories A Thousand Tiny Wings, Survival of the Fittest, Klein's Story and The Architects of History. For the fiftieth anniversary of the show, BBC Radio 4 Extra repeated several stories and broadcast two new stories; Protect and Survive starring Sylvester McCoy and 1963: Fanfare for the Common Men starring Peter Davison. In May 2015, BBC Radio 4 Extra broadcast the first series of Fourth Doctor Adventures starring Tom Baker and Louise Jameson. In 2016, the station broadcast a run of Sixth Doctor adventures: The Crimes of Thomas Brewster (28 May – 4 June),[5]Industrial Evolution (11 – 18 June)[6] and The Curse of Davros (25 June – 2 July).[7]

In 2006 Big Finish began a standalone range of audio plays featuring the Eighth Doctor. These stories were set after his travels with Charley Pollard and C'rizz in the main range, which were subsequently ended.

In 2012, Big Finish began a range of ongoing dramas featuring the Fourth Doctor, as portrayed by Tom Baker. Baker had previously declined to feature in Big Finish releases, but after recording The Fourth Doctor Box Set had been encouraged to participate.
